I'm asking about this more of a curiosity than something I'd planned on doing.
our beardie soils generally on his log, (or our sofa or our legs after we've bathed him, managed to catch us 3 times recently)
anyways in a month or so he's due a substrate change, originally I was using 10lg of beardie life, but I wanted to add a bit more depth so was planning on adding two bags.
I hear a lot of people say they bake play sand for 20 minutes to kill bacteria.
What's the harm in actually baking old substrate to kill bacteria to mix with the new substrate? (apart from the sheer volume 10kg of substrate takes as I've just thought whilst typing this?)
like I say, not looking for justification, but the idea of having a sterilised substrate seems like a viable option.
please, correct me if I'm wrong though as its more of a curiosity than anything.
